Organotin polymers as anticancer and antiviral agents

• Organotin polymers are readily synthesized using the Lewis acid–base concept.
• Organotin polymers inhibit many cancer cell lines.
• Organotin polymers inhibit many DNA and RNA viruses.
• Organotin polymers represent a new class of compounds that control cancers and viruses.
• Organotin polymers are readily synthesized using commercially available reactants.

Organotin polymers are easily synthesized employing interfacial polymerization systems involving the reaction of difunctional Lewis bases and organotin halides. A wide variety of organotin-containing polymeric products have been synthesized including the first water soluble organotin polymers. The organotin polymers exhibit a wide range of biological activities including the inhibition of a wide variety of cancer cell lines including cell lines associated with ovarian, colon, lung, prostrate, pancreatic and breast cancer. Some also inhibit a variety of viruses including those responsible for herpes infections and smallpox. The synthesis, structural characterization, and biological characterization of these materials are described in this review.
